You wash the car and notice bubbles below the doors. Or you catch a curb and leave a dent along the sill. Then you find a cheap replacement rocker panel online and wonder why the body shop wants so much more.
So what does rocker panel replacement cost? Backyard Body Shop in Michigan advertises rocker repair at $1,500 for both sides, or $2,500 with both cab corners. Full replacement needs a closer look at what is damaged.
For comparison, an Iowa Silverado owner shared a $1,500 to $2,000 per-side replacement quote, including paint and cab corners, in February 2020. That older quote is linked below.
I will show you what those prices cover, how slip-on panels differ from full replacements, and how hidden rust changes the job.
What a Body Shop Charges for Rocker Work
Backyard Body Shop in Fruitport, Michigan, publishes these two prices. Both are for work on both sides of the vehicle, checked October 17, 2026:
The shop does not spell out the panel type, paint coverage or inner rust repairs included. You will need a separate quote for a full replacement on your car.
Cab corners are the lower rear corners of a pickup’s cab. If they need work too, you are buying a larger repair than just the long strip below the doors.
Slip-On Panels Versus Full Replacements
A slip-on panel fits over the existing outer rocker. Raybuck sells steel versions that can be attached with adhesive, rivets or welds. Its full replacement panels require the old outer panel to be cut away.
Here are two Raybuck parts for the same driver side of a 2014 to 2018 Chevrolet Silverado or GMC Sierra crew cab. These are aftermarket Key Parts panels:
These prices buy the steel panel. Shipping, tax, fitting, paint and any damaged inner metal still need to be priced. Confirm the cab style as well as the model year before ordering.
A slip-on cover cannot replace missing metal inside the sill. If the inner rocker or reinforcement has rusted through, covering the outside leaves that damage underneath.
Welding alone does not tell you the repair is complete, either. A slip-on can be welded on too. What matters is which damaged metal gets removed and what replaces it.
Why Rust Can Make the Bill Grow
The outer panel is only the part you can see. Behind it are inner panels and, depending on the vehicle, reinforcements. Rust reaching those layers means more than replacing an outer skin.
Mike’s Auto Body in Fall River, Massachusetts, treats surface rust by sanding, treating and repainting. Once rust has eaten through the metal, its repairs involve cutting out the affected section and welding in new steel.
There are limits to where a shop can cut. I-CAR’s guidance for the 2013 Ford F-150 allows sectioning of the outer body side, but not its inner reinforcement panels.
That means replacing just a small piece of reinforcement is not an approved shortcut on that truck. The body shop needs the repair procedure for your particular vehicle.
After the metalwork, Mike’s uses seam sealer and cavity wax to protect the repair. It also recommends keeping drain holes clear. Paint on the outside is only one part of keeping moisture away from the new steel.
If the problem is flaking rust underneath rather than a damaged rocker, my undercarriage rust removal guide covers cleaning and protective coatings.
Does a Dented Rocker Need Replacing?
A curb dent needs a different assessment from rust holes. A dent specialist may be able to reshape sound metal, while a torn panel or damaged reinforcement needs body repair work.
Mike’s uses paintless dent repair for shallow dents with intact paint. Cracked paint, a sharp crease or badly stretched metal can mean traditional bodywork and repainting instead.
I would have the shop identify whether you damaged the metal sill or only its plastic trim. Then ask whether the metal can be repaired under the maker’s procedure before agreeing to replacement.
For dents that can be repaired without repainting, see the paintless dent repair guide. A general dent price is not automatically a rocker-panel price.
What Owners Paid and Were Quoted
These older accounts show how much the scope matters. I kept the dates and the extra work with each price so you can compare them with your own estimate.
- An Indianapolis owner of a 1998 Chevrolet Venture reported a previous $2,500 rocker repair on CarComplaints, published June 1, 2015. Rust was continuing on both sides, inside and outside the van.
- In a September 29, 2015 post, a 2002 Explorer owner in Goffstown, New Hampshire, reported a $1,200 quote for partial rocker and wheel-well repairs. A second shop quoted $1,700 to $2,200 for rocker repair.
- An eastern Iowa owner of a 2004 Silverado crew cab received a $1,500 to $2,000 quote per side for rocker replacement, cab corners and repainting. The February 23, 2020 post tied the price to the damage underneath.
The Explorer’s cheaper quote covered about half of each outer rocker and part of one inner rocker, plus wheel-well work. Neither that owner nor the Silverado owner confirmed a final paid bill in those posts.
What I Would Check Before Spending the Money
Get an itemized quote that identifies the side, the panel and the repair method. It should separate the outer skin from inner metal, floor repairs and cab corners, with paint and corrosion protection included or clearly priced separately.
Agree on how the shop will handle hidden rust before it cuts the outer panel off. Photos of the exposed metal can help you understand why extra work is needed.
For a car you want to keep, I would compare the complete repair with the cost of replacing the car. If the frame, floors and other body panels are also badly rusted, fixing the rockers alone may leave another large bill waiting.
Ask about the rust warranty specifically. Mike’s excludes rust repair from its lifetime workmanship warranty, even though it protects the repaired area. Do not assume a collision-repair warranty covers returning corrosion.
Questions About Rocker Panel Replacement
Can I replace a rocker panel myself?
A full steel replacement involves cutting, fitting, joining and refinishing body metal. It is a job for someone with body repair experience and the vehicle’s repair instructions, not just someone who has bought a replacement panel.
Can body filler fix a rust hole?
Filler can shape a finished repair, but it does not replace missing steel. Mike’s Auto Body warns that covering rust with filler leaves corrosion spreading underneath.
Are rocker panels and running boards the same thing?
No. The rocker is the body section below the doors. A running board is an outside step, and replacing that step does not repair the body behind it.
Is a pair of rocker panels the same as a complete repair kit?
Not necessarily. A pair may contain only the left and right outer panels. Inner rockers, reinforcements, cab corners and finishing materials can be separate.
